Article Summary:

On its blog Sigma has published a preview of its revised 17-70mm f2.8-4.0 DC Macro OS HSM lens. Previous versions of the lens have been popular with APS-C shooters for underwater use as a “scouting” lens. New features which should increase this versatility include macro capabilities with a maximum 1:2.9 magnification (at 70mm) and faster maximum apertures at all focal lengths. Not a new feature, but this version also has Optical Stabilization. However, its minimum focusing distance of 22cm may mean that it will be best used with a diopter.
